2 GB DDR3-1333 for HP Pro desktops

This OWC module adds 2 GB of DDR3 memory running at 1333 MHz with CL9 latency. It is built as a 240-pin non-ECC unbuffered DIMM operating at 1.5 V and is validated for HP Pro 3330, 3400 and 3405 systems.

Check your HP Pro model and memory slots

Confirm the desktop is a Pro 3330, 3400 or 3405 before ordering. Verify the motherboard has a free 240-pin DDR3 slot and that the existing modules also run at 1.5 V. The module is single-rank 1Rx8, so mixing with dual-rank sticks may affect channel population rules.

JEDEC and RoHS compliance mean a straightforward

The memory meets JEDEC standard timings and RoHS requirements, so it works without BIOS tuning or voltage changes. OWC supplies a limited lifetime warranty and free technical support, but no extra software, heat spreader or installation tools are included in the package.

Questions about this item

Does the OWC 2GB DDR3 1333 module ship alone or with any extra parts?

The box contains one 2GB DDR3 1333 PC3-10600 CL9 1Rx8 240-pin 1.5V Non-ECC UDIMM module. No cables, brackets or tools are included; installation uses the motherboard slots directly.

Should I pick the 2GB stick or look for a larger capacity for my HP Pro 3330?

This part is a single 2GB module. If your HP Pro 3330, 3400 or 3405 has free slots you can add more of the same spec, but the listed item only provides 2GB total.

What does the PC3-10600 1333MHz rating actually deliver once installed in an HP Pro 3405?

The module runs at 1333MHz with CL9 latency at 1.5V, giving the standard DDR3 bandwidth for that speed grade. Real-world gain depends on how many slots you fill and the tasks you run.
